Phthalic anhydride (PA) is produced by the oxidation of 0-xylene (CSH10) in a fixed bed reactor at 350°C according to the following reaction: CSH10 + O2 → CsH,O3 + H2O A condenser is used to remove all the PA (C3H,O3) as a mixture of solid and liquid. How many kilograms of o-xylene are recycled per hour if the purge gas is 78% N2 (the balance is a mixture of xylene, air, and H20) and 60% conversion of o-xylene takes place on one-pass through the reactor? Recycle Purge 78% N. 118 kmolihr Air 94 kmolhr REACTOR o-Kylene 6 kmolihr Solid and Liquid PA

Transcribed Image Text:Phthalic anhydride (PA) is produced by the oxidation of 0-xylene (CSH10) in a fixed bed reactor
at 350°C according to the following reaction:
CSH10 + O2 → CsH,O3 + H2O
A condenser is used to remove all the PA (C3H,O3) as a mixture of solid and liquid. How many
kilograms of o-xylene are recycled per hour if the purge gas is 78% N2 (the balance is a mixture
of xylene, air, and H20) and 60% conversion of o-xylene takes place on one-pass through the
reactor?
